本文介绍了一种新的聚合物载体-稀土金属络合物,聚(苯乙烯-丙烯酰胺)载体-钕络合物的合成,表征和讨论了络合物的IR光谱,由此络合物与烷基铝组成的二元体系对丁二烯聚合具有良好的催化活性和定向效应。不同烷基铝的催化活性顺序为Al(i-Bu)_3>Al(i-Bu)_2H>AlEt_3。
This article describes the synthesis, characterization and discussion of the complexation of a new polymer support - rare earth metal complex, poly (styrene - acrylamide) - neodymium complex. The complex The binary system with aluminum alkyl has good catalytic activity and orientation effect on butadiene polymerization. The catalytic activity of different aluminum alkyls is Al (i-Bu) _3> Al (i-Bu) _2H> AlEt_3.
